Sullivan was not evil.
He needed a different structure, but I doubt he would have offed a kid or a person who's vulnerable.
shareI disagree. He was working with an evil gangster and lied to his fellow cops about about a good police officer doing the corrupt things he himself was doing. He murdered 4 people to cover up his crimes and got his compunence from Dignam at the end.
shareI feel if Dignam didn’t exist and Sullivan got away with his past he would’ve become a model cop and in the future a staunch tough on crime prosecutor. He was a lost child who got dragged into the life and it became all he knew since he was a boy.
But you can tell he wanted to move on from the life.
